[QUOTE="KNERSIE, post: 751016, member: 4353"] You are right in the fact that no new genes will be created and the desirable characteristics need to be evident in the base population. When starting out with linebreeding the first step is usually to identify a PROVEN superior sire that is strong in the traits you value and hopefully without visible flaws to a degree you can't live with. The second step is to identify cows that are strong in the traits you feel the bull might be lacking, this will give you enough genetic variation in the base population to be able to select for higher performance by stacking the "good" genes, by eliminating the "bad" ones. You are basically in an ongoing process of rearranging the genes in order to come closer to achieving your ideal animal. I have obviously oversimplified everything for the sake of being brief, but the crux of the matter is to start out with superior animals from the get go. [/QUOTE]
